  • DC Null Voltmeter

    For measuring low voltages especially the differences between two Voltage References I build the DC Null Voltmeter from Conrad Hofman.
    The Mini Metrology Lab, Part 2

    This is a switchable chopper based (LTC1050) DC Amplifier with a max. Gain of 10000!

    For testing i build a Voltage DIvider with an Vishay CNS471A6.
    It is amazing to measure 10µV with common Multimeter in the 100mV Range.

    Here Pictures from the Bench.
